Simple affordable pedal that works just like you want it to. No problems with this pedal in the first 200 miles. I've had other similar Shimano pedals and have been very happy with functionality and durability. Easy instal and cleats fit perfect.

I've put these pedals on my carbon road bike, which I use for moderate weekend riding and sportives and charity rides. I adjusted the tension to make exit easier. Was surprised to find I could not use my park wrench to put these on...no bolt on the pedal shaft! I had to use an Allen wrench to install. Was not a problem, but could make removal a little complicated if I leave them on as long as I did the old pedals I replaced. Overall, very happy with the quality and would recommend to others who prefer spd pedals over the conventional road pedals.

These are great pedals this is my wife's and mine second set. I put a set on our Hybrid/Fittness bikes last year and we loved them. We just bought some road bikes and I just ordered another set for them.

I got 30 thousand miles on these pedals, rebuilt them three times and recently bought another set for my new bike. To rebuild is to unscrew the pedal axel assembly, wipe off old grease, put new grease in pedal body and screw back in the axel assembly. As you tighten the axel assembly, the new grease squeezes out the old grease, wipe it off and you are good for another year. This pedal installs on the bike using 8mm Allen Key, much improved over the 6mm Allen Key and 15mm pedal wrench used on lesser models. Based on Shimano parts lists, I found that this is the cheapest Shimano pedal with all metal parts. The M520 and others have a plastic lock bolt (that requires TL-PD40 Special Tool) and for the average cyclist should be fine. I have many miles on the M520 pedals as well. The upgrade is the metal lock bolt (no special tool needed to loosen) and the M540 is the cheapest model with this upgrade.
